, ERICK, a citizen of the United States, and" 'To all-whom it may'concern:

Be it known that I, WILLIAM A. FRED- resident of Boston, in the countyofSuliolk and State of Massachusetts, have'invented certain new anduseful Improvements in Automatic Oilers, of which the following is aspecification.

This invention is an improvement in automatic oilers of thetype shownand generi cally claimed in my 'copending application 1 Serial No.177,119, filed June 26th, 1917,

and which utilizes the vibration, jarring or other usually-slight bodilymovement of the machines or apparatus to be, oiled, to effect themovement of an oil carrier from a source I of supply to an oil deliverymeans.

In the specific form shown in said application, a wick or. othercapillary device raises tion from which they, may drain by gravitthrough said tube.

My present invention contemplates the use of a wick or other cap' larydevice to receive oil from said oil carrier and which thereby permits ofthe lateral as well as the downward delivery of oil. It also. involves anovel form of support for theoil carrier and certain other features.

With these and other objects in view the improved inventionconsists inthe construetion and combination of parts substantially as hereinafterdescribed.

Of the accompanying drawings Figure 1 represents a vertical sectionthrough my improved automatic oiler in one of its embodlments. g

Fig. 2 is a plan view of the same with with the stopper or cap removed,and with the duct nipple in section.

Fig. 3 represents a section on line 3 '3 of Fig. 1. 1

angle to that of Fig. 4 and stead of a horizontal one. the numeralswhich are thesame as those Figs. & and 5 are vertical sectionalrepresentations of another embodiment of my invention, the section ofFig. 5 being at a right Fig. 6 is a vertical sectional representation ofanother modification.

Similar reference characters indicate the same' or similar parts in allof the views.

' Referring first to Figs. 1, 2 and 3, the

reservoir 10 for the oil, is provided with a suitable cap-or stopper 11,which may be screw-threaded or. otherwise secured in place.) Extendingtransversely ,of'th'e reservoir 10, near its upper end, is atroughshaped guide 12 foran 0il-carrying vibrator 13, which isillustrated as a sphere, but ohviously might be. a short cylinder if theguide were properly shaped.

A wick 1 1 extendsthrough an opening 15 at one end of the guide 12, downinto the oil in. the reservoir'lO Another wick 16 extends over the otherend of the guide 12 out through a duct in the nipple 17.

It will readily-be understood that by capillary attraction oil fromthereservoir 10 has a constant tendency to reach the'upper end of thewick 14. When the machine in which the oiler is attached is in motion,the vibrations ofthe machine cause the vibrator 13 to travel back andforth along the guide 12, and so take oil from the upper end of the wick.14, and transfer it to the Wis]: 16, which willconduct oiltothe oilparticular place to be lubricated. .When the machine is idle orstationary and the parts are requiring no lubrication, the vibrator13will cease to move and therefore there will he no oil conducted ortransferred from one wick to the other..

A small hole 18 in-the guide 17 serves to permit any accumulationofoilon or in guide to return to the bottom of the wearvoir.

In Figs. 4 and 5 I illustrate anemhodiment of the invention designed tosupply lubricating oil through averticalnipple in- In said figures inFigs. 1, 2 and 3, indicate substantially the same features or parts. Insaid Figs. 4 and 5, the wick for conducting the outgoing oil isindicated at 15, and is inclosed in a small tube 19, which communicateswith a port 20 in the base of'the reservoir, the latter communicatingwith a port 2 l-"i n the vertical nipple 17 With this form-g he vibrator13 operates in the same manner; as hereinbefore described in connectionwith Fig. l, to transfer oil from the upper end of the capillary wick 14to the end of the outgoing conducting wick 16.

In Fig. 6 the reservoir 10 having a cap 11*, is provided with a nipple22 having a port 23, the inner end of which is preferably larger thanthe outer end, to accommodate the inner end of the light link 24 whichis pivoted at 25 in the enlarged end of port 23, so as to vibrate, theother end of the link being pivotally connected at 26 to a float 27which serves to support the vibrator 24: above the normal level of oil,a wick 28 is connected in any suitable manner so that one end will moveor rise and fall with the vibrator, the other end of the wick extendingthrough the port 23. When the machine is in operation, vibration of thelink 24 and float 27 will cause the float to efiect more or lesssplashing of the oil in. reservoir 10 and some of the oil will bethereby dashed onto the. vibrator and its wick 28 and then by capillaryattraction feed to the place needing lubrication. The only reason forhaving the wick 28 extend so far down as shown in Fig. 6 is to increasethe amount of oil that will be carried up by capillary attraction. Thevibrator 24 alone would serve for some purposes, as even-a metal linkwill transmit some oil. By extending the wick 28 well down and nearly tothe float to catch someof the oil splashed by the float, there will be agreater amount of oil supplied, as above stated.

This application is a substitute for and continuation of my priorapplication Serial No. 126,415, filed October 18th, 1916.

Having now described my invention, I claim:

1. An automatic oiler having a reservoir provided with an outflow duct,a wick in said duct, a guide adjacent the inner end of the duct, a wickhaving its upper end ad acent the other end of the guide, and a rolleron said guide and free to be vibrated back and forth between the saidwicks.

2. An automatic oiler comprising a reservoir having a horizontal guidein its upper portion, a wick leading from the reservoir to one end ofthe guide, an outflow wick leading from the other end of the guide, anda roller free to vibrate on the guide between the wicks.

3. An automatic oiler having a reservoir,

provided with an outflow duct leading from its upper portion whereby oilin the lower portion of the reservoir cannot escape through said ductunder normal stationary conditions. a wick for transmitting oil throughsaid duct by capillary attraction, said wick bein z'above the normallevel of oil in the re r, a vibrator free to be moved by the ar ngresulting from the operation of thegfmachine carrying the oiler, meansfor supporting the vibrator above said normal level of oil, and meansfor supplying limited quantities of oil to said vibrator fortransmission by the vibrator to the wick.

4:. An automatic oiler having a reservoir and two spaced wicks, one ofsaid wicks being in position to take oil direct from the supply in thereservoir and the other wick being elevated and in position to deliveroil, and a vibrator operated solely by the bodily movement of the oilerto transfer oil from one wick to the other.

5. An automatic oiler having a reservoir, a nipple extending laterallyfrom one side thereof and adapted to be secured to a part having apassagetherethrough, a guide extending transversely of the reservoiropposite the inner end of said nipple, a capillary device for raisingoil from the lower portion of said reservoir to the level of said guide,and a carrier movable back and forth along said guide from saidcapillary device to said passage.

6. An automatic oiler having a reservoir, a nipple extendin'g laterallyfrom one side thereof and adapted to be secured to a part to which oilis to be delivered, said nipple having a passage therethrough, a guideextending transversely of the reservoir opposite the inner end of saidnipple, a capillary device for raising oil from the lower portion ofsaid reservoir to the level of said guide, and a carrier movable backand forth along said guide from said capillary device to said passage,the movement of sa1d guide being due solely to the bodily movement ofsaid oiler and the part to which it is attached.

7. An automatic oiler having a reservoir, a horizontal guide thereinabove the normal level of the oil, a member mounted to roll oiled andthereby subjected to the jarring vibration or other similar movement ofsuch -n1echanism, a pair. of Wicks one leading from the oil to a pointabove the normal 5 liquid level and the other leading to the exterior ofsaid reservoir from a point'above said level, and a vibrator operatingto transfer oil from ope Wick to the other, the movement of sziiclvibrator being imparted thereto solely by the bodily movement of said 1mechanism. v
